Michael Washington, a restaurant owner in Helena-West Helena, Arkansas, was killed on January 5th in what appeared to be a robbery. Polygraph testing of a leading suspect resulted in a confession implicating himself and two others.

Data collected by US Customs and Border Protection shows that the polygraph is effective in identifying criminals applying for badged positions that had been missed by all other screening methods, and that polygraph screening significantly cuts the incidences of post-hiring malfeasance over candidates who did not undergo the polygraph test.

A Texas inmate who reported a plot against Senator John Whitmire, is in trouble after prison officials discovered the inmate was actually faking the report in hopes of gaining reward. Polygraph exams administered during the course of the investigation revealed the informant's true intentions.
